The DTL/DML Mission Control System (MCS) Demonstrator

Introduction

Within the previous PECS project "Advanced SCOS-2000 Monitoring" ANF DATA participated on the development of ESA Ground Operations S/W (EGOS) generic libraries covering the management and transfer of telemetry packets.

The purpose of this follow up activity is to verify the new EGOS Data Transfer and Data Management libraries (DTL/DML) within a mission control system. The telemetry reception and telemetry distribution chain of the existing ESA Mission Control System SCOS-2000 will be re-engineered adopting these libraries.

The overall ESA project ‘DTL/DML MCS Demonstrator' is performed by Siemens Austria as a prime contractor within the GSTP program, and ANF DATA as a subcontractor within the PECS program.

The project started in December 2007 and its duration is planned until January 2010.

Description

The main benefit of the new architecture is that the server components based on the generic EGOS DTL/DML libraries will not depend on the existing SCOS-2000 libraries. This will allow reuse the new server components not only within a mission control system but also within other systems in the ESA ground segment.

In addition, a more flexible concept for cascading data distributors will be implemented for live data packet distribution. The specific SCOS-2000 distribution concept represented by the centralized packet distributor servers (CPD) and packet archiving distributor servers (PDS/PARC) will be replaced by a generic distributor implementation.

The new telemetry chain will be compared to the existing SCOS-2000 telemetry chain regarding performance and maintainability. The end-to-end test of the telemetry chain will be performed with the automated testing framework ART (Automated Regression Testing).

It is expected that the new architecture developed in this activity will bring increased maintainability and flexibility.
